Welcome to Musically Intelligent Machines autotagging API. Get started by registering or logging in. This API is for non-commercial use and is limited to 50 tracks per day. Please contact us if you would like to use it more than this limit or for commercial purposes.
The API can give you html results or, more usefully, JSON results. You can use the http arguments "format=json" for any page to get a json formatted version of it. Or follow the links in the pages. At the moment, the system can only process mp3s.
